Ownership verified by DX Great little device to have with you everywhere
Posted by willybgood on 3/16/2010
Involvement: Expert (understands the inner workings) - Ownership: more than 1 month

Overall Rating: starstarstarstarstar

Pros: I had device for over a year now, just recent bought it again on DX because one of the antennas broke. Like others have said, it works extremely well with t-mobile phones. ATT is kind of iffy because I know I have knocked out many iphone users, but at work when i turn it on and ask to see my friends ATT phone, it still says full bars. I have yet to try out on Verizon, but it has worked on and off on Sprint phones. I live in California and it has shipped twice to me with no problem.

Cons: Be careful with the antennas because they can break if bent. The DCS antenna has no effect in the US so no worries if you break that. I would warn against using the included car charger because it has shorted out one unit I bought and left it useless.

Other Thoughts: The unit seems to work very well in inclosed areas. Though as i have seen, it works well in open areas such as on the freeways, which i like to use to stop driving people from talking. It also lasts for around 2-3 hours with varied use so use sparingly.

Bottomline: You need to get this device, and for under 26 bucks, how can you beat this devices price point?

Ownership verified by DX nyc no effect on boost mobile or iphone

Pros: This device worked out the box. Killed my bran new behold 2 dead. T-mobile is extremely affected by this i mean maybe 5 m or 15 ft. Went for a walk killed some ny not others. On the bus it kills the people right next to me or behind. 2 Rigs or more people still talk.

Cons: Train i did see a thugish character eating and making a loud annoying smacking sound. Knew he would be trouble with a cell in his hand. He hi send i powered up an blam cut him off it was a great feeling. Go next to a chatter box within 1 meter on boost an nothing happened. Friend at work has iphone made a story service was out in some areas he went for his phone i powered up an his call went through. Mixed emotions on device. But something is better than nothing. Walking in pocket results were the same.

Other Thoughts: Can't say it wasn't worth it. First device like this i bought. If i knew 100% another similar device would take out the carriers this device can't i would buy it. But none of the reviews really help with that decision. For the price how can u beat ig. I seen same device selling from #50 and up. Bottom line not jumping for joy but not disappointed either. I am ok with it.

Bottomline: Since they aren't legal no way to get it factory tuned to us carriers. Result is not every cell phone will b blocked. But i can guarantee onetime an obnoxious talker is near me i will be pushing on that power faster Than i can hit the return key on my computer.

Ownership verified by DX Product is great, shipping took 3 weeks

Pros: Small metal case and looks solid enough. It works well at close range. A car length.

Cons: I have no issue with the product itself. The order sta at the supplier for 4 days before being shipped. I watched the airmail tracker and it looks like it sat at the Hong Kong post office for over a week. The next tracking point was in the U.S. Post office port of entry in NJ and it looks like it sat there for almost a week. I was wondering if it would be confiscated. It finally showed up at my house. Not really sure Dealextreme has any control over that part. It was worth the wait since it was a real bargain.

Other Thoughts:

Bottomline: I am happy with my purchase.

Pros: WORKS with blocking USA AT&T 3G and Verizon CDMA networks confirmed!!! great idea to include a card adapter. Cant wait to stop my mom from using her phone when she's in the care with me. Drives me nuts!!!

Cons: none yet, just got the product yesterday. The power button could have been placed better...

Other Thoughts:

Bottomline: I was skeptical. First of all, It made it into the USA and passed customs, and it works! Blocks my iPhone w/ ATT and also Verizon CDMA network. Still testing full range, but can atleast go abt 15ft for sure, even through the ceiling if i leave it in living room below me!
